Curiosity Series 166 — Mizuno ALTIUS 01 FEELS

Karry September 21, 2024 0

I’ve finally completed my collection of all the high-end models currently in production from Mizuno. From the first 01F in the Olympic colorway to its successor, the 01FS, it truly forms a symbolic echo. For someone like me who has always been pursuing niche high-end models independently, completing a brand’s entire high-end range is a task that demands considerable time, effort, and money. Knowing that I would lose a lot financially, I still went ahead with it. If not for passion, it would have been impossible to achieve.

Specs: 4UG6, total weight (without grip tape) 90.9g, balance point 304mm, mfusion shaft 210mm, medium-stiff tuning, handle length 201mm, full-groove 76-hole aerodynamic frame, tension warranty 27lbs, strung at 27lbs with NBG98 string.

The 01FS still features the iconic design style of the Altius series, with a glossy white base coat that exudes a silky smooth texture, delicate like handling something precious. Although it, along with the 11P/Q, represents the latest model in its respective series, the changes are fewer compared to the FT series—essentially, it’s just a color update. This time, the 01FS uses sky blue fonts and watermark colors. To summarize, in the Altius series, J1 has the most unique paint job. Excluding the Olympic version, the other high-end models only differ in color: 01F is gold, 01S is purple, 02S is red, and 01FS is blue, making them quite easy to distinguish.

When I first started reviewing Mizuno’s latest high-end series, I didn’t pay much attention to their frame expertise. Now, I think the frame design is one area where the brand has invested significant effort. The 01FS doesn’t adopt the wide Regrove head shape of the J1, 02S, and FT series but instead continues with the tapered head design from the 01 series. The aerodynamic treatment of the frame is not overly aggressive. Except for the slightly sharper design at the T-joint, all other areas transition naturally into a fluid box-type frame, which also makes the frame thickness seem relatively low. In terms of dry swings, the racket feels swift, with a noticeable head-heavy sensation that aligns with the balance point specifications. The racket uses the T8-grade carbon fiber from the 01 series. Although the shaft has the standard 210mm length and medium stiffness, the 9mm shorter handle often gives me the illusion that the racket feels more responsive and stiff. The BCS and full-groove design are still present.

I previously wondered if the 01FS would be just another 01S or simply a version of the 01F with a shorter handle. However, the feedback during hits proves that it’s not. Compared to the 01F, the 01FS feels more direct, and perhaps due to the shorter handle, it provides a sense of quicker, more immediate response. At the same time, the head-heavy feel is stronger than the 01S, and shots feel weightier. In terms of power transfer, the 01FS surpasses the 01S, which, from my recollection, often required a bit more effort when hitting the shuttle. During warm-up clears, I felt that the FS leans more towards the FT series, with the current weight distribution being very close to the Fortius 10 Power. It’s easier to generate power with the 01FS, making it particularly useful in doubles, where I preferred using controlled high clears to make less-experienced opponents uncomfortable during baseline exchanges.

As mentioned earlier, the 01FS has a distinct direct-response characteristic and may be the racket with the most authentic feel in the series—this aspect is somewhat reminiscent of the 01Speed. As a result, it no longer belongs to the purely control-oriented category like the 01Feel. The reduced “sweetness” increases its aggressiveness. However, in terms of control, the 01FS still delivers top-tier performance. The enhanced feedback allows users to quickly adjust touch during repetitive net play, stabilizing shots like net dribbles, pushes, and flicks, and offering excellent feel during delicate maneuvers.

Regarding its aggressiveness, I believe the FS achieves this through faster response. Securing a higher hitting point is often the prerequisite for a quality shot, and the key to using the 01FS is to attack early. The racket’s total length is just 666mm, making it feel more nimble than other head-heavy rackets. This agility shines in contesting fast exchanges during serves and returns, as well as in drive attacks. Flicks to the backcourt, pushes down the waistline, and drives to both sides are all executed effortlessly. It’s the hidden cunning behind its elegant appearance.

The 01FS retains the same close-range combat advantage as the 01Speed in the mid-to-front court, producing crisp shots with excellent shaft recovery speed. Although the head-heavy feel can make it a bit slow to react during higher-tempo situations, its overall performance remains excellent, and it can still serve well as a speed racket.

The only slight drawback might be its smashing power, though it’s more than adequate. The direct nature of its shots, combined with the noticeable head-heavy feel, provides straightforward performance. The shaft’s explosiveness maintains the expected Altius level, but in terms of offensive efficiency, it likely doesn’t surpass the J1 or Fortius series. Instead of relying on a single decisive smash, it’s more effective to adopt a continuous, varied approach—two or three quick smashes followed by a drop shot or a sudden drive after a net smash. This kind of strategy feels natural. “Weighted agility” is the overall impression the 01FS gives me, allowing me to continuously diversify my scoring options in fast-paced exchanges. It even evokes a “wildcard” sense of unpredictability.

Yes, this new Altius model might just be the most satisfying overall. To conclude this chapter with Mizuno, I feel content.
